蒙古国克鲁伦河流域土地利用与土地覆盖现状分析

为构建我国北方疆域生态安全防御体系提供理论依据,以蒙古国克鲁伦河流域作为研究区,利用Path-Row=130-27的TM遥感影像数据,采用PCI、Erdas、ArcGIS等遥感及地理信息系统软件,对近年的土地利用与土地覆盖现状进行分析。通过非监督分类及目视解译,得到调查区林地、草地、灌木林、湿地、农田、水体、城镇七大土地利用类型及其分布特征;探讨了蒙古国克鲁伦河流域土地利用与土地覆盖变化的空间分布规律,得出草地占据主要类型,面积为44.8%,城镇、工矿用地占极小比例,畜牧业是该地区的主要经济活动方式。

Analysis on the Land Use and Land Cover in Kherlen River Basin, Mongolia

This research took the Mongolian Kherlen River basin as the research area,using remote sensing data of TM Path-Row=130-27 and the geographic information system software,such as PCI,ERDAS,ArcGIS and so on., to analyze the current situation of land use and land coverage in the Kherlen River basin.Through the non-surveillance classification and the visual interpretation,this paper obtained seven types of land use and its distribution characteristics.The seven types were forest,grassland,shrub,wetland,farmland,water and urban.And this paper also discussed the spatial distribution rules of land use and land cover in the Kherlen River basin.It can come to a conclusion that grassland is the main type of land cover and its area reaches 44.8 %,the percentage of urban and miner land use was little.So stockbreeding was the main economic activity in this area.
